All speakers have a little EQ built in

It may come as a shock to audio purists but part of the work of a crossover is level matching as well as tonal adjustments of individual drivers.  Ahem.  That's what we call equalization. 

This is true whether the speaker uses active or passive crossover, and may be in place just to adjust phase matching in the crossover range.

Also, curiously, while companies may brag about the number of parts in their crossovers, more parts does not indicate more quality.  It may just indicate more equalization had to be done to the drivers to get them to match.

@carlsbad2  Oh, I prefer a smooth and objectively neutral treble as well.

 

OTOH, Dali for instance, is making big strides by lifting up their treble response.  I think there is a market for that, for hearing loss but also for low-level listening.

I replaced my speaker’s level controls recently,

vintage electrovoice 4 way, 16 ohm L-Pads (not potentiometers). Pair labeled Presence and Brilliance

vintage AR-2ax, two pairs of speakers, 3 way: two 8 ohm L pads each pair. Also renewed the AR-2ax crossover capacitors. Electrovoice crossover is components in a metal can full of tar. I’ve been advised by custom crossover makers to leave them alone.

then I use a microphone, ear level seated position, with tracks 9 to 28 from this GRP/Carver test tone CD

 

 

then spent a day and a half carefully balancibg them so frequencies not only blended equally but frequencies do not vary side to side

Oh no!  Please say it ain't so...  I guess if they all got it right all speakers would sound the same.   Long live EQ!

All costly speakers sound "high end " if they are high end ...

No need for EQ nor any acoustics concepts not even need to own some ears  ... The price tag say it all and the owner manual ...😉
